BRIEF DESCRIPTION OF THE DRAWINGS

The present disclosure will become more fully understood from the detailed description and the accompanying drawings, wherein:

FIG. 1 is a functional block diagram of a computing network including an example computing device according to some implementations of the present disclosure;

FIG. 2 is a functional block diagram of the example computing device of FIG. 1; and

FIG. 3 is a flow diagram of an example technique for user identification of and translation of media according to some techniques of the present disclosure.

DETAILED DESCRIPTION

As previously mentioned, a user may access a website that displays a web page including text, images, audio and/or video data, or a combination thereof. Given the worldwide reach of the Internet, the web page may have been created in a language that the user cannot understand. For example, the user may be unable to read text or subtitles of a video stream or the user may be unable to understand an audio stream. The user, therefore, may request to translate a portion of the web page (text, video subtitles, audio, etc.) from its source language to a target language that the user can understand.

Accordingly, techniques are presented for user identification of and translation of media. The techniques can generally provide for a more efficient method of user identification of and translation of media, which can improve a user's overall experience. The techniques also provide for identification of and translation of only a portion of media item that the user cannot understand, instead of translating the entire media item. The techniques can receive, at a computing device including one or more processors, a user input (i) identifying a portion of a media item and (ii) indicating a request to translate the portion of the media item from a source language to a target language. The term “media item” as used herein can refer to a digital item capable of being output at the computing device. The term “media item,” therefore, can include text, video, audio, or a combination thereof. A media item including at least one of audio data and video data can also be referred to as a “media stream” because the media item may be streamed for a period of time. In response to the user input, the computing device can transmit the portion of the media item, e.g., a text, to a translation server via a network. The computing device can then receive a translated portion of the media item, e.g., a translated text, from the translation server via the network. In some cases, the media item may be a media stream, and the techniques can further include determining the text corresponding to a portion of the media stream, which can then be transmitted to the translation server via the network.

It should be appreciated that the techniques of the present disclosure can be executed a plurality of times during a particular period, e.g., during the media stream. In other words, the user may provide the user input a plurality of different times to identify different portions of the media item for translation. The techniques can then transmit these different portions of the media item to the translation server for translation. For example, the techniques can transmit the different portions sequentially or in one or more groups. Similarly, the techniques can then receive different translated portions of the media item from the translation server. For example, the techniques can receive the different translated portions sequentially or in the one or more groups. Each portion may also include a unique identifier for associating the portion of the media item (pre-translation) to its corresponding translated portion. The computing device can then output the different translated portions in any suitable manner (sequentially, in the one or more groups, etc.). For example only, the user may identify a plurality of portions of a media stream and, after the media stream has completed, the user can review the translated text for each of the plurality of portions.

Referring now to FIG. 1, a computing network 100 including an example computing device 104 according to some implementations of the present disclosure is illustrated. It should be appreciated that the term “computing device” as used herein can refer to any suitable computing device including one or more processors (a desktop computer, a laptop computer, a tablet computer, a mobile phone, etc.). The computing device 104 can receive input from and/or provide output to a user 108. The computing device 104 can communicate with other computing devices via a network 112. The network 112 can include a local area network (LAN), a wide area network (WAN), e.g., the Internet, or a combination thereof.

In particular, the computing device 104 can communicate with a server 116 via the network 112. It should be appreciated that the term “server” as used herein can refer to either a single server or two or more servers operating in a parallel or distributed architecture. The server 116 can be configured to perform translation of a text from a source language to a target language. The server 116, therefore, can be referred to hereinafter as translation server 116. The translation server 116 can perform translation of the text from the source language to the target language using any suitable language translation technique. For example only, the translation server 116 can translate the text from the source language to the target language using statistical machine translation (SMT).

According to the techniques of the present disclosure, the user 108 can provide a user input at the computing device 104. The user input can (i) identify a portion of a media item and (ii) indicate a request to translate the portion of the media item from a source language to a target language, which is described in further detail below. In response to the user input, the computing device 104 can transmit the portion of the media item, e.g., a text, to the translation server 116 via the network 112. The computing device 104 can then receive a translated portion of the media item, e.g., a translated text, from the translation server 116 via the network 112.

Referring now to FIG. 2, a functional block diagram of the example computing device 104 of FIG. 1 is illustrated. The computing device 104 can include a user interface 200, a communication device 204, a processor 208, and a memory 212

The user interface 200 can receive input to, e.g., from the user 108 and/or provide output from the computing device 104. It should be appreciated that the term “user interface” as used herein can refer to any suitable components for receiving input and/or providing output. For example, the user interface 200 can include a mouse, a keyboard, and/or a display.

The communication device 204 can control communication between the computing device 104 and other devices via the network 112. The communication device 204 can include any suitable components for communication via the network 112, e.g., a transceiver. In particular, the communication device 204 can control communication between the computing device 104 and the translation server 116 via the network 112. More specifically, the communication device 204 can transmit a text to the translation server 116 via the network 112 and can receive a translated text from the translation server 116 via the network 112.

The processor 208 can control operation of the computing device 104. It should be appreciated that the term “processor” as used herein can refer to either a single processor or two or more processors operating in a parallel or distributed architecture. For example, the processor 208 can perform functions including, but not limited to loading and executing an operating system of the computing device 104, controlling information input and/or output via the user interface 200, controlling communication over the network 112 via the communication device 204, and/or controlling read/write operations at the memory 212. The memory 212 can be any suitable storage medium (flash, hard disk, etc.) configured to store information at the computing device 104.

The processor 208 can also execute the techniques according to the present disclosure. The processor 208 can execute the media item to provide output (text, audio, video, etc.) to the user 108. During the outputting of the media item, the user 108 can provide a user input to the computing device 104 that (i) identifies a portion of the media item and (ii) indicates a request to translate the portion of the media item. The user input can include one or more mouse clicks, one or more keyboard keystrokes, or some combination thereof. Other suitable user input configurations can also be implemented. The specific user input can be predefined or specified by the user 108, and may be stored at the memory 212. The user input can also depend on the type of media item being output. For example, when the media item includes only text, e.g., a text-only web page, the user input may be one or more mouse clicks at or near a portion of text. Alternatively, for example, when the media item is a media stream including audio data and/or video data, the user input may be one or more keyboard keystrokes.

In response to receiving the user input, the processor 208 can obtain or capture the portion of the media item identified by the user input. The portion of the media item can also depend on the type of media item being output. For example, when the media item includes only text, the user input can cause the processor 208 to capture the portion of text within a predefined distance or area from the one or more mouse clicks. Alternatively, for example, when the media item is a media stream including audio data and/or video data, the user input can cause the processor 208 to capture the portion of the media stream (its audio data and/or video data) for a predetermined period prior to when the user input was received. Other suitable rules specifying how to capture the portion of the media item can also be implemented.

As previously mentioned, when the media item is a media stream including at least one of audio data and video data, the processor 208 can also determine a text corresponding to the audio data and/or video data for the portion of the media item. For example, the processor 208 can perform voice/speech recognition to determine the text from the audio data for the portion of the media item. Any suitable voice/speech recognition techniques can be used. Additionally, in some cases the video data can include subtitles for corresponding audio data. In these cases, the processor 208 may also determine the text from the subtitles in the video data. For example only, the processor 208 can perform optical character recognition to determine the text from the subtitles in the video data. Other suitable image-to-text conversion techniques can also be used.

Additionally, after the communication device 204 has received the translated text from the translation server 116, the processor 208 can control the manner in which the translated text is presented to the user 108 via the user interface 200. Specifically, when the media item is a media stream, the processor 208 can capture the portion of the media item and receive the translated text from the translation server 116 before the outputting of the media stream has completed. In these cases, the processor 208 can wait until the media stream has completed before outputting the translated text via the user interface 200. Alternatively, the processor 208 can output the translated text immediately upon receipt from the translation server 116 or a predetermined period after receipt. Further, the processor 208 can control additional information that is presented to the user 108 via the user interface 200, such as the text for the portion of the media item (pre-translation), a definition, related words/phrases, hyperlinks to Internet-based language resources, and the like.

Referring now to FIG. 3, a flow diagram of an example technique 300 for user identification of and translation of media is illustrated. At 304, the computing device 104 can receive a user input (i) identifying a portion of a media stream being output at the computing device 104 and (ii) indicating a request to translate the portion of the media stream from a source language to a target language. At 308, the computing device 104 can transmit the portion of the media stream to the translation server 116 via the network 112 in response to receiving the user input. Specifically, the computing device 104 can transmit a text corresponding to the portion of the media stream to the translation server 116 via the network 112. In some implementations, the computing device 104 can determine the text based on the techniques previously discussed herein (optical character recognition, voice/speech recognition, etc).

At 312, the computing device 104 can receive a translated portion of the media stream from the translation server 116 via the network 112, the translated portion of the media stream having been translated from the source language to the target language by the translation server 116. Specifically, the computing device 104 can receive a translated text from the translation server 116 via the network 112, the translated text having been translated from the source language to the target language by the translation server 116. At 316, the computing device 104 can output the translated text. In some implementations, the computing device 104 may wait until the media stream has completed before outputting the translated text. The computing device 104 can also output additional information as previously discussed herein. The technique 300 can then end or return to 304 for one or more additional cycles.
